If you can't manage to tech and keep a stacked tube poppit running I am not sure how if you plan to keep anything running. No offense at all, there are many things other people find very easy I cannot figure out for the life of me. All I am saying is that if your don't over think it, modern guns are a breeze to work on if they ever need work.

Here is what I suggest:
Want something with some girth to it and a great smooth shooter? Alias.
Want something newer without macroline? G6r
Want something you will rarely have to tech? Ego 9-11
If you are okay with having to lube a little more often though I suggest the Marq series from bob long. Not too light, thick but not too thick frame, fast as you need.
